I was putting a Magpul ASAP ambidextrous sling mount on my new AR and used alot of caution when taking it apart. All went well until the reassmbly. As I was screwing in the buffer tube the retaining pin popped up and the spring is no where to be found. I've moved everything around in the garage and am about to shop vac it to see if I can pick it up. However, I'm betting it's lost. I have the buffer retainer but have lost the spring. I was concentrating on keep the sling mount against the lower so I wouldn't lose or kink that spring that I must have not had the tube far enough in. Where can I find one without having to buy a whole kit? Any help would be appreciated. I'm more disappointed in myself for being careless than the loss of the spring.
